The handler trait users implement to receive messages.

Required Methods

fn on_message<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 MessageContext, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Called for each inbound user message.

Provided Methods

fn on_sync_buf_updated<'life0, 'life1, 'async_trait>( &'life0 self, _sync_buf: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Called when get_updates_buf changes — persist it here.

fn on_start<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Lifecycle hook: called before the poll loop starts.

fn on_shutdown<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Lifecycle hook: called after the poll loop ends.
